Stoma prolapse after formation of an ileostomy or colostomy is a late complication. Prolapse is less common than parastomal hernia. This article reviews the incidence of prolapse, technical factors related to the construction of the stoma that may influence the incidence, and different options for repair. Stoma prolapse affects 2%-47% of individuals with ostomies. Transverse loop colostomy has the highest rate of stoma prolapse, especially because of the large redundant distal loop. Loop ileostomies were thought to have a higher prevalence rate in the past, but recent literature shows only a 2% prolapse rate for ileostomy as opposed to 47% for loop colostomy. The role of extraperitoneal stoma construction is uncertain. Fascial fixation and size of the fascial defect have not been proven to affect the incidence of prolapse. Local care of stoma prolapse is possible, especially if stoma is not incarcerated; however, reversal of stoma is preferable if possible. The options of surgical repair include reversal, resection, revision, and relocation. Semin Colon Rectal Surg 23:13-16 © 2012 Elsevier Inc. All rights reserved. D espite substantial advances in surgical technique and enterostomal therapy, complications after stoma creation remain extremely common. The rate of stoma-specific complications in the literature varies widely, ranging from 10% to 70%. 1-5 Stoma complications can be divided into early and late complications. Of the late complications, parastomal hernias are more common than stoma prolapse. Predisposing factors for development of stomal prolapse can be identified as patient factors, technique, and location of ostomy. This review describes the incidence of prolapse and assesses the technical factors related to the construction of the stoma that may influence this incidence. The different methods of repair have also been outlined.
